Hello! i have two datalist controls, datalist1 which is the parent control and datalist2 which is the child control. They are both retrieving data from two related tables(primary/foreign). I want both datalists to respond to one edit, cancel, update and delete button, which are on the parent/outer datalist control. For now the delete button can delete data from both, but now i cant get the two datalists into edit mode from the edit button that is in the itemtemplate of the outer datalist. please who can help, i have done alli know to do, and even browsed. been on it for two weeks now. Thanks in advance.

    C#:

    protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
            {
                foreach (DataListItem listitem in DataList1.Items)
                {
                    DList = listitem.ItemIndex;
                }

                if (e.CommandName == "Edit")
                {
                    DataList1.EditItemIndex = e.Item.ItemIndex;
                    var list = (DataList) DataList1. Items[DList].FindControl("DataList2");
                    list.EditItemIndex = e.Item.ItemIndex;
                    DataList1.DataBind();
                    list.DataBind();
                }
                if (e.CommandName == "Cancel")
                {
                    DataList1.SelectedIndex = e.Item.ItemIndex;
                    DataList1.EditItemIndex = -1;
                    DataList1.DataBind();
                }
                if (e.CommandName == "Update")
                {
                    //EditAchievementDataList.SelectedIndex = e.Item.ItemIndex;
                    //string username = User.Identity.Name;
                    //int userAchievementid = Convert.ToInt32(EditAchievementDataList.DataKeys[e.Item.ItemIndex]);
                    //TextBox achievement = (TextBox)e.Item.FindControl("AchievementLabel");
                    //AchievementManager.UpdateAchievement(username, achievement, userAchievementid);
                    //EditAchievementDataList.EditItemIndex = -1;
                    //EditAchievementDataList.DataBind();
                }

                if (e.CommandName == "Delete")
                {
                    DataList1.SelectedIndex = e.Item.ItemIndex;
                    string username = User.Identity.Name;
                    int doctorateid = Convert.ToInt32(DataList1.DataKeys[DataList1.SelectedIndex]);
                    DoctorateManager.DeleteDoctorate(username, doctorateid);
                    DataList1.DataBind();
                }
